Magnitude 7.7 earthquake
Affected countries: The Bahamas, Cayman Islands, Jamaica, Haiti, Honduras, and Cuba
87 miles from Montego Bay, Jamaica * 2:10 PM

So far no word of a tsunami threat. A quake that size could cause a significant tsunami depending on whether it was a slip-strike fault or a normal or reverse. The latter two would cause water displacement that could lead to a major tsunami, with little time to warn the affected areas.
